Burrumbuttock Lime Trial Site

The replicated farm-scale trial site was established to monitor the medium to long term benefit of early intervention acid soil management on a moderately acidic soil that is traditionally a low priority for liming. The trial consists of 7 treatments investigating 4 different liming rates of 0.5 t/ha, 1 t/ha, 2.5 t/ha and the ‘one-in-a-generation’ 6 t/ha, as well as the effect of lime incorporation compared to surface applied. A total of 28 plots (7 treatments replicated 4 times), 70 m × 9 m in size, were marked out in early 2020 and NSW DPI used their direct drop spreader to apply the lime on the plots.
